"Maybe J.C. Hallman's book should have been titled WWJD II: What William James Did -- Part 2. Hallman's book alternates between sketches of James' life and ideas and Hallman's own voyages into the back bays of our nation's spiritual life… The Devil Is a Gentleman ventures into some bizarre territory…[including] a strangely moving account of the birth of a German shepherd puppy." Dallas Star-Telegram
